What is the primary quantitative trade-off in energy allocation for reproduction?
Answer
Quantity versus quality of offspring
Since energy is finite, an organism faces a trade-off: investing heavily in many small offspring (quantity) diverts resources from self-maintenance or growth, whereas investing in fewer, larger offspring (quality) demands more energy per unit but yields higher survival probability.
